SNAP-HOOK;

To all whom it may concern:

Beit known that I, VICTOR F. Nansen, a subject of the King of Great Britain, residing at Spokane, in the county of Spokane and State of Washington, have invented new and useful Improvements in Snap- Hooks, of which the following is a specification.

The invention relates to hooks, and more particularly to the class of snap hooks.

The primary object of the invention is the provision of a snap hook of this character in which there is arranged a guard for closing the hook, so as to prevent any possibility of the removal of a strap or other member connected therewith, the guard being locked against accidental opening movement.

Another object of the invention is the provision of a snap hook of this character in which the operating member for the guard will be incased, so that it will be impossible to accidentally move the slide, but it is capable of being readily operated by hand, so as to open the hook when desired.

A further object of the invention is the provision of a hook of this character which is simple in construction, efficient in its purpose, devoid of complicated parts, and that may be manufactured at a minimum expense.

lVith these and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

In the drawings Figure 1 is a side eleva- 'tion of a snap hook constructed in accordance with the invention. Fig. 2 is a fragmentary vertical longitudinal sectional Fig. 3 is a sectional view on the line 33 of Fig. 1. Fig. 4 is an edge elevation.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

The invention may be embodied in a variety of forms, and therefore it is not to be limited in its application. However, in order to present a concrete embodiment for illustration, there is shown a snap hook, comprising a body 5, the same being provided with a channel or recess 6 opening through one side thereof and also one of its Specification of Letters Patent.

ends, the said recess being closed by a removable section 7, correspondingly shaped to the body. Formed integral with the body and projecting outwardly therefrom in the same plane therewith a hook 8, the bill 9 of which terminates spaced from the body and is formed with a cutaway portion 10 at its inner side.

Upon the body 5 in the same plane therewith and projecting outwardly therefrom on the side opposite the hook S is an eye or loop extension 11, to which is adapted to be connected a strap (not shown), in the ordinary well-known manner.

Arranged within the recess 6 is a slide 12, the same being formed with a rounded outer end 13 which protrudes slightly through the open end of the body 5, the said open end of the body and the end of the section 7 adjacent thereto being provided with dished notches 14 which permit the fingers of the hand of a person to readily grasp the rounded end 18 of the slide, or the thumb of such hand to force the same inwardly within the recess, for a purpose presently described.

Formed on the slide and projecting through a slot 15 intersecting the recess 6 in the body is a guard 16, the outer end thereof being cut away, as at 17, so that the bill 9 of the hook 8 and the said guard 16 will overlap each other, when the guard is in position for closing the hook.

Fixed to the inner end of the slide 12 is one end of a bowed leaf spring 18, the opposite free end of which is normally engaged with a shoulder extension 19 of a wearing plate 20 fixed against one side wall of the recess 6. Thus, by reason of the engagement of the spring 18 with the shoulder extension 19, the slide will be locked against inward movement, thereby sustaining the guard 16 closed, and prevented from accidental opening.

Provided in the closed end of the body 5 .and communicating with the recess 6 is a cavity 21, in which is arranged a releasing latch, comprising a beveled block 22, against the beveled face of which rests the free end of the spring 18, the block 22 being formed with a stem 23 projected through a suitable aperture 24 formed in the closed end of the body 5, so that on pressing the finger of the hand of an operator upon the stem 23 the beveled block 22 will depress the free end of the spring 18 out of the path of the shoulder extension 19 of the wearing strip 20, thereby unlocking the slide 12 and permitting it to be pushed inwardly within the recess 6 for opening the guard 16, whereupon the free end of the spring 18 will play upon the Wearing strip 20, and on releasing the slide 12, the latter will be forced outwardly through the open end of the slot, thereby bringing the guard in position for closing the hook 8, and the free end of the spring will again move into locking engagement with the shoulder extension 1.9 of the wearing plate 20, thus locking the guard against movement.

The section 7 is detachably mounted upon the body 5 for the closing of the recess 6 therein by. means of removable screws 25, one of which is passed through an elongated guide slot 26 formed in the slide 20, so as to guide the slide in its movement within the recess in the body.

From the foregoing, taken in connection with the accompanying drawings, it is thought that the construction and operation Copies of this patent may be obtained for five cents each, by addressing the Commissioner of latents.

for normally holding the guard closed and having a free end, means within the body and engaging the free end of the spring means to hold the slide locked, and means for releasing the spring means from the last-named means.

In testimony whereof I affiX my signature in presence of two witnesses. v
